No spoiler review!
Anyone who grew up with DOOM and DOOM II will appreciate what id has done with this version. It truly is "Hell on Earth" with a few subtle nods to the original 90's sequel, but updated to keep in line with the current franchise.
One of the most notable things that deviates from lots of other games is you start off with some tricks and weapons early on, instead of starting over from scratch every. Single. Time. (I'm eyeing you specifically, Metroid)
Most of the controls have been maintained since DOOM and a slightly different layout makes it easy and quick to learn new abilities and moves. I'm usually slow to learn new controls and while this is no exception, right now it's just a matter of remembering that I have new things to use rather than remembering which button does what.
The game runs awesome too. I haven't noticed any usual overheating issues with my CPU and GPU. Also, don't let the specs scare you off, I'm currently running this on a 2nd gen Intel i5 with an nVidia GTX970, a Samsung 840 EVO SSD, and 16gigs of Gskill RAM. Most of my graphics settings are on High/Ultra and there was only one point where I noticed a stutter, but it might have been something else running in the background on my system. Granted, a much more up to date system will run the game even better, but as long as you're running a system within the past five-ish years, you should be fine. The game loads quickly and loading game files is also very quick, much improved over DOOM 2016 load times that seemed to take forever. Though, building a new rig is in my near future.
There were a few hiccups and I was able to solve both issues. First, if the game absolutely refuses to load, like you hit 'play' and nothing happens, make sure your graphic drivers are up to date. I was behind by a few updates and once I updated them, it loaded with no issue.
There is also an issue using bluetooth headphones. The game will refuse to play any sound if you are using bluetooth headphones. There are many fixes out there, but everything I tried did not work and as I went through the list, none of them were fixes for bluetooth headphones, only wired headphones. So, I ran a wire up to my headphones and the sound works normally. I am hoping this is only a temporary issue and a later patch will address this.
Overall, despite those two minor issues, the game has been enjoyable and definitely holds up to its predecessor. So, go out, get yourself a copy and rip and tear until it is done.
